The Jo-Ral 4A Bass Trombone Straight Mute made of spun aluminum, and has been tested to perform evenly in all registers. Jo-Ral mutes also feature neoprene-enhanced composite cork pads that provide extra durability. The result is a more pliable cork that grips well and doesn’t dry out, become brittle or break off—so it lasts longer while easily accommodating fine adjustments for a perfect fit.
Features:
- Fits all bass trombones
- Crafted from lightweight spun aluminum
- Pliable neoprene-enhanced composite cork pads offer lasting durability and grip
